CHAPTER 5 EXPERIMENTATION 5.1 Spur gear terms and concept Fig. 5.1 Terminology definitions for spur gears The radial distance from the pitch circle to the outside diameter is called as addendum. The radial distance between the pitch circle and the root diameter is called as dedendum. The distance of the arc along the pitch circle from one side of a gear tooth to the other is called as circular thickness. The length of the arc of the pitch circle from one point on a tooth to the same…

ABSTRACT Solubility is the phenomenon of dissolution of solid in liquid phase to give a homogenous system.Solubility is one of the important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response to be shown. Poor watersolubledrugs often require high doses in order to reach therapeutic plasma concentrations after oral administration. Low aqueoussolubility is the major problem encountered with formulation development of new chemical entities. Any…

is struggling, there is no point in pouring billions of dollars a year into an energy source that is killing our other resources. This kind of spending and reckless destruction of our environment will eventually have to stop. The question is, when burning burning fossil fuels ultimately ceases, where will we turn? There are many forms of alternative energy that are accessible to us right now. These energy sources will eventually have to be used in the place of burning fossil fuels to provide…

as a traditional solar thermal system by producing hot water directly from solar irradiance and storing it in the WST. This system can work independently when there is sufficient solar irradiance to heat the WST. The other loop functions as a heat source for the IDX-SAHP initiating if there is not enough solar irradiance to heat the WST completely although it is able to heat the liquid –cooling evaporator leading to the heat pump as well as charging the PCM when the heat pump is turned…

Vandalism or defacement of public property is an ongoing problem and the end is not yet over. The issue of vandalism is not to be underestimated by all levels of society. Vandalism is not only wrong legally, it is one of the negative events that go wrong in the religion of Islam. In the holy Quran, Allah says “But seek, through that which Allah has given you, the home of the Hereafter; and [yet], do not forget your share of the world. And do good as Allah has done good to you. And desire not…

developer uses natural resources like water, river-belt, or site-specific facilities to generate hydroelectricity. Therefore, users need to pay some fee to the government for the use of such natural resources, which is one of the non-tax revenue sources for the government (Gautam, Karki…

Kate Byrne DT299/4 CHEM 4128 Applied Physical & Analytical Chemistry Assignment Liquid Chromatography High Resolution Mass Spectrometry Hyphenated Techniques The term “hyphenated technique” was introduced by Hirschfeld in 1980. It refers to the combination of a chromatographic separation technique and a spectroscopic detection technique to form a new, more efficent instrument. The technique which will be discussed in this case is LC-MS. The aim of combining both techniques is to purify and…

For the synthesis of P2, a mixture of 1 (500 mg, 0.553 mmol), 2 (252 mg, 0.553 mmol), 3 (760 mg, 1.105 mmol), tris(o-tolyl)phosphine (P(o-tol)3) (13 mg, 0.044 mmol), and tris(dibenzylidene acetone)dipalladium(0) (Pd2(dba)3) (10 mg, 0.011 mmol) in anhydrous chlorobenzene (21 mL) was charged in a 100 mL round bottom flask. The resulting reaction mixture was heated at 150 °C under stirring for 3 days. Compound (2) (38 mg, 0.083 mmol) was added and stirred at 150 °C for 1 h. To that…

An electron vacancy is created and is further filled by an electron from the higher shell and thus an X-ray is emitted to balance the difference in energy between the two electrons. The detector placed on the energy dispersive spectroscope apparatus measures the number of emitted X-rays and their energies. Energy of the X-ray is characteristics of the element from which X-ray is emitted. A spectrum of the relative counts of the detected X-rays is obtained and evaluated for quantitative…

Tesla and Edison During the late 1890s the inventions of two great minds, Nikola Tesla and Thomas Edison, helped turn electricity from a scientific concept into a household amenity. In this paper, I will review both of these men’s lives, give an overview of their accomplishments, and go over how these accomplishments still have an impact today. Nikola Tesla was born July 10, 1856 in Smiljan, Croatia. A bright child with an almost photographic memory and an aptitude for problem-solving, Tesla…
